Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a document creating apparatus having a display unit of one or several lines that cannot faithfully display input characters at a specified print size.

[0002]

[Prior art]

 Conventionally, as this type of document creation apparatus, for example, a simple one such as a small word processor or an electronic typewriter can be used.

A display unit such as an electronic typewriter is composed of an LCD (abbreviation of a liquid crystal display) and, unlike a CRT or the like, is sized to display only one or several lines of character strings. ing.

[0004] Unlike an expensive and large-sized one such as a word processor having a display such as a CRT, a small-sized and easily-priced one can be used for simple applications. It is for setting.

[0005] Incidentally, such an electronic typewriter also has a function of enlarging or reducing only a certain character in a certain character string, for example, to emphasize the character.

In connection with this function, it is desirable to display characters faithful to the designated print size on the display unit. For this purpose, an expensive LCD with a high resolution (dot density per inch) is used. Conventionally, the display unit simply displays all the input characters in a fixed size regardless of the specified print size, while the print size is It was configured so that what it was was separately displayed on a part of the display unit.

The display of the print size is configured such that, when a character to be inputted is designated by a key, the print size is displayed on a part of the display unit. The processing is performed based on the specified print size.

[0008] As described above, the document creation device such as the electronic typewriter described above is configured to express an accurate print image at a printing stage rather than at a character input stage. The display unit was configured at low cost without complicating the display unit.

[0009]

[Problems to be solved by the invention]

 However, the conventional example having such a configuration has the following problems.

[0010] The print size of only characters to be input is displayed on the display unit, and the print size of already input characters is not displayed. The print size of cannot be confirmed during character input.

[0011] Therefore, after finishing the character input, it is necessary to confirm which character has what print size after actually printing, and it is necessary to correct the print size of the inputted character again. In some cases, it was very inconvenient and workability was poor.

The present invention has been made in view of such circumstances, and allows a user to confirm the print size of input characters in the middle of character input without using an expensive display unit. The purpose is to save the trouble of printing to confirm.

[0013]

[Means for Solving the Problems]

 The present invention has the following configuration to achieve such an object.

That is, the present invention has a plurality of printing sizes of characters, and displays characters at a fixed size on a display unit composed of one line or several lines, and displays characters displayed on the display unit. In a document creation device having a function of displaying a print size set for a designated character by designating with a cursor, an input unit for inputting a character and setting and inputting a print size for the character, and the input unit Setting means for setting the printing size to a predetermined character size before inputting character data from the user, storing each character data input by the input unit, and setting the relevant text only in the preceding stage of the character data to be stored. Storage means for storing print size data set for character data; and storage means for storing a character designated by a cursor in a character string displayed on the display unit. Size extraction means for extracting print size data at the preceding stage of the corresponding character data from the display section, and a size display section provided at or near the display section for displaying the print size extracted by the size extraction section. I have.

The operation of the configuration of the present invention is as follows.

Before the input of the character data, the printing unit sets the print size to a predetermined character size. After that, when the character data input from the input unit and the print size set for the character are stored in the storage unit, the cursor is returned to the already input character and the desired character is designated by the cursor. The print size for the character pointed to by the cursor is extracted and displayed.

In other words, even if a character is already input, the print size of the character pointed to by specifying it with the cursor during the character input is accurately displayed. Confirmation is possible, and therefore, there is no need to separately perform printing as in the past. In addition, the storage of the character data and the print size data in the storage means is such that the print size data set for the character data group is stored only before the character data group including one or more character data to be stored. Therefore, the amount of data to be stored can be reduced as much as possible, so that the storage capacity of the storage means can be reduced to a necessary minimum.

[0018]

[Embodiment of the invention]

 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 to FIG. 10 show an embodiment of the present invention.

FIG. 1 is a plan view schematically showing the appearance of the document creating apparatus. In the figure, reference numeral 1 denotes a display unit composed of an LCD, which is configured to display a character string of several digits in one line in this embodiment. Not only the input character string is displayed on the display unit 1, but also the print size of the input character is displayed at one end in the longitudinal direction of the display unit 1 (in the rightmost three digits in FIG. 1). It is displayed as a character of the same size as.

Reference numeral 2 denotes a cursor display unit provided below the display unit 1. The cursor display unit 2 allows a cursor KS to designate one pixel, half a pixel, and an inter-pixel of the display unit 1. It is configured to be able to do it.

Reference numeral 3 denotes an input operation unit including a character key, a numeric keypad, a space key, and various control keys. Reference numeral 4 denotes a cursor movement key for one pixel, and reference numeral 5 denotes a cursor movement key for half a pixel.

The one-pixel cursor movement key 4 is used to move one pixel on the display unit 1, that is, to confirm the print size of an already-entered character, which will be described later. The cursor movement key 5 is used for moving half a pixel and designating between pixels on the display unit 1, that is, for designating a reduced character or inserting a character to be described later.

It is not always necessary to separately provide the cursor movement key 5 for half a pixel. For example, a combination of the cursor movement key 4 for one pixel and another key can be used instead.

FIG. 2 is a configuration block diagram of the document creation device. In the figure, reference numeral 6 denotes a CPU to which the above-described components are connected via an interface (not shown), reference numeral 7 denotes a ROM in which a program for controlling the CPU 6 is written, and reference numeral 8 denotes an input from the input operation unit 3 or the like. This is a RAM for storing various data.

The CPU 6 fetches external data from the input operation unit 3 through an interface (not shown) according to a program in the ROM 7 or performs data processing with the RAM 8 while exchanging data with the RAM 8. The processed data is output to the display unit 1 and the printing unit 9 via an interface (not shown). The ROM 7 stores a program for checking the print size of the input characters and inserting a new character between the input characters, and the like, and the RAM 8 stores the input character string. And at least an input buffer area for storing the print size of each character of the character string.

Next, a procedure and an operation for inputting a character will be described with reference to FIGS. 3 and 4. FIG. 3 shows a flowchart for explaining the operation at the time of character input, and FIGS. 4A to 4F show display examples.

First, when the operator sets the character input mode, in step S10, the print size of the character to be input is set to the standard "full-width", "full-width" is displayed at a predetermined position on the display unit 1, and in step S11, The cursor KS is set below the first pixel (the left end of the display unit 1 in the figure) of the display unit 1 in the cursor display unit 2 (see FIG. 4A). At the same time, as shown in FIG. 5, "full-width" is stored as the print size at the head of the input buffer area of the RAM 8.

Therefore, for example, for a character string such as “Be careful of the following points”, the print size of “Caution” is doubled in width, and the other character strings of “To the next point” and “To.” An example in which all print sizes are set to the standard full size will be described.

Since “full-width” has already been set as described above, when the operator first operates the character keys to input “next balance”, a character code is given from the input operation unit 3 to the CPU 6. Can be Therefore, the type of the input code is determined in step S12, and the process proceeds to step S13 for a character code, to step S14 for a print size code, and to step S15 for a control code. In this example, since the character code of each character of "next ten" is associated with the depression of the character key, the character code corresponds to the print size data stored in the input buffer area of the RAM 8 one by one in step S13. In step S16, the cursor KS is shifted to the right by one character, and the process returns to step S12 to wait for the next input code. Needless to say, instead of processing all the characters of "next tenni" at one time, the processing is performed by repeating steps S12, S13, S16 and S17 one character at a time [see FIG. 4 (b). ].

In step S14, when a code for designating a print size is input, a new print size is stored in the input buffer area of the RAM 8, and the print size is displayed in step S18. In step S15, a process according to the control code is performed, and the process returns to step S3.

Subsequently, when the operator presses the kana-kanji conversion key, the kana-kanji conversion code is given to the CPU 6. Therefore, the determination is made in step S12, the process proceeds to step S15, and the kana-kanji conversion processing of "next tennni" to "next point" is performed. The KS is set at the lower part of the pixel immediately after the last character of the "to the next point" character (see FIG. 4 (c)).

When the operator calls a print size menu with a predetermined key of the input operation unit 3 and designates the print size before inputting the next character, the print size code is given to the CPU 6 and the print size code is given in step S12. Since the code is determined to be a code, the flow advances to step S14 to store "double size" as print size data after the character data "NI" in the input buffer area of the RAM 8 as shown in FIG. "Full-width" displayed in the rightmost area of "" is displayed again as "double-width". Subsequently, when the operator performs a character input operation and a kana-kanji conversion operation, "caution" is displayed in the same display size as the "next point" by the same processing as described above, and the cursor KS is displayed at the end of the "caution" character. It is set below the pixel immediately after “me” (see FIG. 4D). This "caution" is stored next to the print size data stored in the RAM 8.

Further, since the remaining “Yes” is input in “full-width”, the operator calls the print size menu again and designates “full-width” to change the print size. In step S12, the print size code is determined, and in step S14, "full-width" as print size data is stored after the character data "meaning" in the input buffer area of the RAM 8 as shown in FIG. Then, the "double width" displayed in the right end area of the display unit 1 is displayed again as "full width" (see FIG. 4E). Subsequently, when the operator inputs "do" with the character keys, the process is performed in steps S12, S13, S16 and S17 in the same manner as "to the next point", and "do" is performed as shown in FIG. It is stored after the print size data n stored in the input buffer area of the RAM 8, and “Yes.” Is displayed after “Caution” on the display unit 1, and the cursor “KS” is displayed at the end of the character “Yes.”. Is set below the pixel immediately after "" (see FIG. 4 (f)).

The character data of “note the following points” input in this manner is stored in the input buffer area of the RAM 8 in correspondence with the respectively designated print size data. This is shown schematically in FIG.

As shown in the drawing, “full-width” is added to the first print size data l, and “next point” is added to each of the subsequent character data l + 1. "Note" is added one character at a time to the next character data m + 1,..., "Full-width" is added to the third print size data n, and "Character data n + 1... "Is stored for each character. Therefore, the character size "full-width" is set for the character data group consisting of the character data of "next character", and the print size data is stored before the character data group. Similarly, the character size “horizontal double width” is set for the character data group composed of each character data of “NOTE”, and the print size data is stored before the character data group, and each of “SU”. The character size “full-width” is set for the character data group consisting of character data, and the print size data is stored before the character data group.

In order to confirm the print size of the already input character while the character input is proceeding as described above, the cursor KS is moved by the cursor movement key 4 for one pixel of the input operation unit 3. The print size of this character is displayed at a predetermined position on the display unit 1 simply by positioning it below the character to be checked.

A specific operation for confirming the print size of the input characters will be described with reference to FIGS. 6 and 7. FIGS. 6A and 6B show display examples of the subroutine for explaining the operation at the time of checking the print size.

For example, from the state shown in FIG. 4F, a case where the print size of “su” of “note the following points” is checked and a case where the print size of “note” is checked are exemplified. I will explain it.

When the operator successively presses the cursor movement key 4 for one pixel in order to set the cursor KS located immediately after “.” Below “su”, the input operation unit 3 The cursor movement code for one pixel is given to the CPU 6. The CPU 6 determines the type of the input code in step S20. In this example, the CPU 6 determines that the input code is the cursor movement code for one pixel, and proceeds to step S21 to shift the cursor KS to the left by one pixel. Steps S20 and S21 are repeated to set the cursor KS at the lower part of "", as shown in FIG. 7A, and the process proceeds to step S24. If it is determined in step S20 that the input code is a half-pixel cursor movement code, the flow advances to step S22. If the cursor KS is shifted by half a pixel, and if it is determined that the input code is another code, the flow advances to step S23. Perform the processing according to.

In step S24, after checking the character pointed to by the cursor KS, it is determined in step S25 whether or not the character exists. If there is, the process proceeds to step S26. Make a warning sound. In this example, since there is a character indicated by the cursor KS, the process proceeds to step S26, where character data corresponding to the character indicated by the cursor KS is searched from the input buffer area of the RAM 8, and print size data of the character data, that is, "full-width" is obtained. The process proceeds to step S28.

In step S 28, the currently displayed print size is compared with the extracted print size data. If the print size data is the same, the display of the print size is kept unchanged without changing the display, and the process returns to step S 20. In this case, the process proceeds to step S29, the print size is changed to the extracted size, and the process returns to step S20.

In this example, in the state shown in FIG. 4 (f), no character has been input above the cursor KS and the print size of “Yes.” It is determined that the data is the same as the extracted print size data, and the process returns to step S20 with "full-width" being displayed on the display unit 1 as shown in FIG.

Then, when the operator presses the cursor movement key 4 twice for one pixel from the state shown in FIG. 7A, the processes of steps S20 and S21 are repeated twice, and the cursor KS is positioned below the “note”. Is moved, and then the processes of steps S24, S25, and S26 are performed, character data corresponding to the character indicated by the cursor KS is searched from the input buffer area of the RAM 8, and the print size data of the character data "Wide double angle" is extracted, and the process proceeds to step S28.

In step S 28, it is determined that the print size displayed before the cursor movement is different from the extracted print size data, and the flow advances to step S 29 to change “full-width” displayed before the cursor movement to the step S 29. The print size data extracted in S26 is changed and displayed, that is, "horizontal double width" (see FIG. 7B).

As described above, according to the present embodiment, the print size can be displayed based on the character pointed to by the cursor simply by returning to the already input character and designating the cursor. The print size can be easily checked. Therefore, it is not necessary to print and confirm the print as in the related art, and the workability can be improved.

Next, a specific operation when a new character is inserted between input characters will be described with reference to FIG. 8 and FIG. FIG. 8 shows a subroutine for explaining the operation at the time of inserting a character, and FIGS. 9A and 9B show specific display examples.

A case will be described in which a “gi” having a full-size print size is inserted between “next” and “no” in the input character “Note the following.”

First, in order to position the cursor KS in the state of FIG. 7B between “next” and “no”, the operator moves the cursor movement key 4 for one pixel and the cursor movement key for half a pixel. Operate 5 At this time, a cursor movement code for one pixel and a cursor movement code for a half image are sequentially given to the CPU 6. Since the CPU 6 determines that the input codes sequentially inputted in step S30 are the cursor movement code for one pixel and the cursor movement code for half a pixel, the steps S31 and S32 are repeated to sequentially move the cursor KS, and The cursor KS is set at the position of, that is, between "next" and "of" (between pixels), and the process returns to step S30 to wait for another input code.

Subsequently, the operator inputs the character to be inserted, that is, “gi”. The printing size of this character is the same as the characters before and after the part to be inserted unless the printing size is specified. Determined the same. That is, in this case, since both “next” and “no” have been input in full-width, as shown in FIG. 9A, “full-width” remains displayed in the right end area of the display unit 1. In other words, when inserting full-width characters as in this example, the characters can be input as they are without changing the print size. However, when inserting characters of other print sizes, it is necessary to call the operator's print size menu and specify the desired print size. If the print size is specified, the print size code is determined in step S30, the print size data is stored in the input buffer area of the RAM 8 in step S36, and displayed in the right end area of the display unit 1 in step S37. Change the displayed “full-width” to the specified print size.

Therefore, the operator operates the character keys to input “gi” without specifying the print size. Then, the CPU 6 determines in step S30 that the character is a character code, and determines in step S33 whether or not the cursor KS is set between characters. When YES is determined, the process proceeds to step S34. The process returns to step S30, and waits for a half-pixel cursor movement code for moving the cursor KS between characters.

In step S 34, the “gi” is input to the right of “next”, and in step S 35, all input characters following “no” are shifted right by one pixel at a time in FIG. As shown in (2), "Note the following points" is displayed on the display unit 1, the contents of the input buffer area of the RAM 8 are changed in accordance with the insertion, and the process returns to step S30.

As described above, the cursor KS is set between characters, that is, at the position where the cursor KS is to be inserted immediately, so that the cursor KS is positioned before or after the position where the cursor KS is to be inserted as in the related art. Not only is there no need to define insertion positions such as setting to characters, but operability can be improved because there is no ambiguity.

When the character string created by the above processing is actually printed, the result is as shown in FIG.

The description of the operation in the above embodiment is merely a specific example, and it goes without saying that the present invention can be variously modified as needed. For example, in the above embodiment, the print size is displayed at one end in the longitudinal direction of the character display unit 1 as a character having the same size as the display character. The visibility can be improved, for example, by making the confirmation visually easier.

[0056]

[Effect of the invention]

 According to the present invention, the following effects are exhibited.

[0057] Even if a character is already input, it is possible to display the print size of the character pointed to by the cursor simply by specifying it with the cursor on the display unit or another size display unit. Usability is improved, for example, the size can be easily confirmed during character input without having to print out as in the past.

[0058] Therefore, it is possible to save work of printing and improve workability, which contributes to accurate and simple character input. Moreover, the storage means is designed to store the print size data set for the character data group only before the character data group consisting of one or a plurality of character data to be stored. This is advantageous in terms of cost and speed, for example, since the required data can be reduced as much as possible, and the storage capacity of the storage means can be reduced to the minimum necessary.
